It is all around us, and we breathe it every day to stay alive. But how "clean" is the air that we breathe? While we know that it contains oxygen, hydrogen and nitrogen, there may be other substances in the air around us that we do not know about... such as dust, mites, spores, bacteria and hazardous fumes.
Air pollution is not just an outdoor problem. Contaminated air inside a workplace can lead to major health problems... long-term exposure to contaminants can cause asthma and even emphysema. In fact, indoor air quality is enough of a concern that the Environmental Protection Agency (EPA) and the National Institute for Occupational Safety and Health (NIOSH) have created an Indoor Air Quality Guide.
"Indoor Air Quality" shows employees the potentially harmful effects of poor air quality, and will help them prevent, identify and correct air quality problems. Areas covered in the program include:
* The sources of air contamination.
* Adhesives, solvents and vehicle exhaust.
* How a building's occupants affect indoor air quality.
* Smoking and second-hand smoke.
* The use of humidifiers and dehumidifiers.
* Pollutant pathways, including air ducts and crawlspaces.
* Heating and air-conditioning systems.
* The symptoms and signs of poor air quality. |
